Conditionally Disabling GZIP in Order to Serve ESI

[Edit: ESI + GZIP can now be supported in certain circumstances. Please contact support@fastly.com to discuss turning this on. Note: You will require a paid account and a TLS product with us in order to do this].

Fastly’s version of Varnish currently doesn’t support the use of ESI with GZIP. But you can conditionally disable GZIP in order to serve ESI when it’s appropriate for your service.
